The specimens collected include four individuals of <em>O.</em> <em>edulis</em> and three individuals of <em>M.</em> <em>gryphoides</em> from the Sağlam village area, and one individual of <em>H.</em> <em>hyotis</em> from the Sarıca village area in Eğil.

For the Sağlam village area, <em>O.</em> <em>edulis</em> suggests a littoral environment with excessive detrital inputs, ranging from medium to shallow depths, and a warm subtropical climate. The <em>O.</em> <em>edulis</em> display a slender, small, and comparatively regular morphology, suggesting a preference for stable habitats commonly found in coastal regions with minimal environmental variability. Similarly, the presence of the fossil species indicates littoral environments characterized by nearshore shallow depths, low-energy conditions, normal salinity, and warm subtropical climatic conditions for <em>M.</em> <em>gryphoides</em>.

Macroscopic features revealed that preservation of these fossils (e.g., intercellular spaces, iron oxides, quartz crystals, colors, and weathering conditions) shared many similarities to some petrified trunks in Tak Province. We investigated both large (approx. 0.50–0.7<!--> <!-->m wide, at least 10–20 meters long) and small fragments of fossils for both wood anatomical features and mineralogy. Diffuse porosity with indistinct growth rings and wide vessels at low densities suggest a tropical lowland forest paleoenvironment.
